Abstract Droughts can strongly affect grassland productivity and biodiversity, but responses differ widely. Nutrient availability may be a critical factor explaining this variation, is often ignored in analyses of drought responses. Here, we used standardized nutrient addition experiment covering 10 European grasslands to test if full‐factorial nitrogen, phosphorus, potassium affected plant community inter‐annual variation stress the extreme summer 2018 Europe. We found that amplified...
With a growing human population facing multiple global change drivers (i.e. climate and land management change), the future of food security is major importance. Sustainable agriculture therefore key to ensure supply under climatic conditions. Forage provision (composed forage quantity quality) an important ecosystem service grasslands for dairy production. However, monitoring quality in semi-natural species-rich rarely done due inherent complexity determining quality, high variability...
Mountainous grassland soils are considered one of the most unique biological hotspots, rich in organic carbon (OC). At same time, they exposed to great threats, as climate warming is more pronounced mountainous regions than lowland areas. In this study, we assessed effect simulated (+1K, +2K, and + 3 K) on OC stocks soil structure Northern Limestone Alps Germany by translocating plant-soil mesocosms from high- (1260 m a.s.l., Rendzic Phaeozem) mid- (860 a. s. l., Haplic Cambisol)...
The increasing prevalence of drought events in grasslands and shrublands worldwide potentially has impacts on soil organic carbon (SOC). We leveraged the International Drought Experiment to study how SOC, including particulate (POC) mineral-associated (MAOC) concentrations, responds extreme treatments (1-in-100-year) for 1 5 years at 19 sites worldwide. In more mesic areas (aridity index > 0.65), SOC POC concentrations decreased by 7.9% (±3.9) 15.9% (±6.2) with drought, respectively, but...
High-elevation ecosystems will experience increasing periods of above-average warmth and altered precipitation changes because climate change. This causes uncertainties for community properties such as productivity biodiversity. Increasing temperature may increase by growing season length metabolic rate or decrease causing drought stress. Competitive outcomes between species change with climatic conditions, shifts in composition. study investigates the resistance aboveground biomass plant...
Warming in mountain regions is projected to be three times faster than the global average. Pronounced climate change will likely lead species reshuffling plant communities and consequently ecosystem resilience functioning. Yet, little known about role of inter‐ versus intraspecific changes traits their consequences for functional richness evenness under change. We performed a downslope translocation experiment intact plant‐soil mesocosms from an alpine pasture subalpine grassland Swiss...
Higher biodiversity can stabilize the productivity and functioning of grassland communities when subjected to extreme climatic events. The positive biodiversity-stability relationship emerges via increased resistance and/or recovery these However, invader presence might disrupt this diversity-stability by altering biotic interactions. Investigating such disruptions is important given that invasion non-native species events are expected increase in future due anthropogenic pressure. Here we...
Warming in mountain regions is projected to occur three times faster than the global average. Recently, a small number of observational studies have reported species loss plant communities and explored mechanisms facilitating colonization by novel species. We monitored translocated their competitor interactions following five years exposure downslope climates. found increasing turnover under two future climate scenarios with time. Local native was followed after severe drought year third...
Abstract Warming due to climate change is generally expected lengthen the growing season in areas of seasonal and advance plant phenology, particularly onset leafing flowering. However, a reduction aboveground biomass production reproductive output may occur when warming accompanied by drought that crosses critical water deficit thresholds. Tracking warmer temperatures has been shown be species‐specific with unknown impacts on community composition productivity. The variability species’...
Abstract Plant community biomass production is co‐dependent on climatic and edaphic factors that are often covarying non‐independent. Disentangling how these act in isolation challenging, especially along large gradients can mask soil effects. As anthropogenic pressure increasingly alters local climate resource supply unevenly across landscapes, our ability to predict concurrent changes plant processes requires clearer understandings of independent interactive effects soil. To address this,...
Abstract The data set contains information on aboveground vegetation traits of > 100 georeferenced locations within ten temperate pre-Alpine grassland plots in southern Germany. grasslands were sampled April 2018 for the following traits: bulk canopy height; weight fresh and dry biomass; percentage plant functional types (PFT) non-green vegetation, legumes, non-leguminous forbs, graminoids; total green area index (GAI) PFT-specific GAI; water content; carbon nitrogen content (community...
Semi-natural, agriculturally used grasslands provide important ecologic and economic services, such as feed supply. In mountain regions, pastures are the dominant agricultural system face more severe climate change impacts than lowlands. Climate threatens ecosystem functions, aboveground net primary production [ANPP] its nutrient content. It is necessary to understand of land-management on ecosystems develop management practices sustainably maintain provision services under future climatic...
Not all colours are perceived and interpreted equally. The electromagnetic spectrum is differently by the distinct visual systems of animal species, resulting in differences each species' colour perception. Given diverse found flowering plants, it interesting to consider perception insects co-evolution plants attract pollinators. Here, we considered between human that bees flies-the two largest insect pollinator groups. We collected flower reflectance spectral data 73 species across seven...
Abstract Warming as a climate change phenomenon affects soil organic matter dynamics, especially in high elevation ecosystems. However, our understanding of the controls mineralization and dynamics remains limited, particularly alpine (above treeline) subalpine (below grassland Here, we investigated how downslope (warming) upslope (cooling) translocations, 5-years reciprocal transplanting experiment, respiration its temperature sensitivity (Q10), aggregation, carbon (C) nitrogen (N)...
Although the functional mix of housing and work promises to create compact settlement structures, impact job-creating commercial developments on demand is not sufficiently managed in current practice. As a result, there often an imbalance between units labour force, which articulated increased for new land take. The authors take this as starting point develop four-stage model, subject article. This model seeks systematically determine effects with jobs residential space provide basis...
Global change drivers such as anthropogenic nutrient inputs simultaneously alter biodiversity, species composition, and ecosystem functions above ground biomass. These changes are interconnected by complex feedbacks among extinction, invasion, shifting relative abundance. Here, we use a novel temporal application of the Price equation to separate richness biomass through time quantify functional contributions that lost, gained, persist under ambient experimental addition in 59 global...
